The cost of scanning, converting, and digitizing content seems to decline every year. As a result, we're seeing all sorts of print archives being converted to digital products. The problem is that too many publishers are applying the "if you build it, they will come" approach to these archives.
Simply creating the digital archive might be good enough for a small market of professional researchers, but it will never attract the larger consumer audience; flipping virtually flipping through stacks of old content loses its appeal fairly quickly.
